Cordyline plant named &#39;Lilly&#39;

ABSTRACT

A new and distinct cultivar of  Cordyline  plant named ‘Lilly’, characterized by its upright to semi-upright plant habit with leaves initially erect to outwardly arching; moderately vigorous growth habit; long lanceolate variegated leaves with brown and yellowish white-colored longitudinal stripes; and excellent keeping quality and good garden performance.

Botanical designation: Cordyline australis.

Cultivar denomination: ‘LILLY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Cordyline plant, botanically known as Cordyline australis and hereinafter referred to by the name ‘Lilly’.

The new Cordyline plant is a naturally-occurring whole plant mutation of Cordyline australis ‘Choc Mint’, not patented. The new Cordyline plant was discovered and selected by the Inventors from within a population of plants of ‘Choc Mint’ in a controlled greenhouse environment in McGraths Hill, New South Wales, Australia during the spring of 2009.

Asexual reproduction of the new Cordyline plant by micropropagated cuttings in Tumbi Umbi, New South Wales, Australia since January, 2010 has shown that the unique features of this new Cordyline plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Cordyline have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lilly’. These characteristics in combination distinguish ‘Lilly’ as a new and distinct Cordyline plant:

1. Upright to semi-upright plant habit with leaves initially erect to outwardly arching.

2. Moderately vigorous growth habit.

3. Long lanceolate variegated leaves with brown and yellowish white-colored longitudinal stripes.

4. Excellent keeping quality and good garden performance.

Plants of the new Cordyline differ primarily from plants of the parent, ‘Choc Mint’, in leaf color as plants of ‘Choc Mint’ have greyed purple and green-colored leaves. In addition, plants of the new Cordyline have narrower leaves than plants of ‘Choc Mint’.

Plants of the new Cordyline can be compared to plants of the Cordyline australis ‘Torbay Dazzler’, not patented. In side-by-side comparisons, plants of the new Cordyline differ primarily from plants of ‘Torbay Dazzler’ in leaf color as plants of ‘Torbay Dazzler’ have green and yellow variegated leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Cordyline plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Cordyline plant.

The photograph on the first sheet comprises side perspective view of a typical plant of ‘Lilly’ grown in a container.

The photograph on the second sheet is a close-up view of a typical plant of ‘Lilly’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in August in 20-cm containers in a polyethylene-covered greenhouse in Keysborough, Victoria, Australia and under cultural practices typical of commercial Cordyline plant production. During the production of the plants, day temperatures averaged 18° C. and night temperatures averaged 8° C. Plants were 18 months old when the photographs and botanical description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
